TO ALL WI-IOM IT MAY CONCERN:

Be it known vthat I, JAMES H. VASI NORTWICI-, of Sturgis, in the county mit.. Joseph, and Stute of. Michigan, have invented certain new and useful Improvements in Wind-Wheels; und I do hereby declare that the following is :i full, clear, and exact description thereof, reference being had to the accompanying drawings. land to the letters of' reference marked thereon. which form n part of this speciiication, in which- Figure l is a plan view oi' the external surface of the pinne of my wind-wheel Figure 2 is a plan view of one of the wings` with pinion attached.

Figure .3 is a view of the main shaft, with the wings atta-cited.

Figure 4 is a plan view of main or driving-wheel, with lever attached.

Figure 5 is a. perspective of the frame of' my machine when viewed at an angle above its upper surface.

Figure is :t similar view of the sume, with the wings removed. Y

Figure 7 is zi' plan view ofthe spring, andplate to which said spring is fastened.

The frame of my machine consists ofthe circular top A and bottom B, furnished with circular projections, C. The vtop and bottom are held together by four ties, d, which pessthrough the projections or ears c, as seen in iig. 5. g designates a vertical shaft, which is pivoted nt its upper end in screw vc, which passes through the top, A. At its lower end the said shaft rests in a metal box, which is placed in the centre oi' the upper: surface of bottom, i To shaft y :1re attached the four wings m, which nre placed equidistunt apart. n represents a. series of wings, which are pivoted at top to A. und passingl at bottom through B. The rounded neck of euch wing, n, projects suiiiciently fui below the surface of' B to have the pinion's nttaeliedto it, the scid pinions being supplied with cogs only on halfl their circumference, (see fig'. l.) These several pinions are operated by d1iving-wlieel H. The' driving-Wheel H is pivoted at thecentre .of B, undvbe'ing geared into all -the pinions s, the whole of the piuions, and the wings to which they nrenttuched, willbe operated at the same moment. In order to adapt the wings n to the direction ofthe wind, the lever E is lfastened to the projecting eentreni` wheel H. The moving,r ofthe said lever moves the driving-wheel to t-lie desired position, and as the ilriving-wheel acts on the p inions s, und the wings n,. to which said pinions are attached, the seid wings will be placed in the position desired by the operator. -'lo keep the lever stntionury when placed in the proper place, a spring, a, is pirovided, (see fig. 7.) The said spring is fastened to the plate p, at right angles with said plate, und boltedto the under surface of B; the spring a being direotly'under the lever E. Several indentutions are in platep, into any one of which the spring a can rest, und thus be prevented from' moving. Averticul shaft can be coupled with the shalt y, lwith a drum on it to give motion to the-required machinery.

'lhe grent advantage I claim for my wind-wheel is the facility with which the wings Cun be adapted to the direction of the wind.

Having thus described my invent-ion, what I claim as new, ond'desire to secure by-LettersrlPatent, is-

Thc combination und arrangement of windwheel m, wings n n, pinions es, wheel H, lever E, spring a, and platep, or its equivalent, substantially for the purpose described.

In testimony thut I claim the foregoing ns my own, I affix my signature in presence of two witnesses.
